A prison's problems with new psychoactive substances (NPS) have led to high levels of violence, according to a HM Inspectorate of Prisons report which said that the availability of ‘legal highs’ could also overwhelm health services at HMP Ranby, in Nottinghamshire. The report highlighted six suicides in seventeen months. NPS chemically mimic drugs that are already banned. The jail holds 1,000 men. Too many are held in large house blocks, with staff saying they felt unsafe. The number of violent incidents, including assaults on staff, was higher than in other similar establishments. The National Offender Management Service said that since an inspection in September the number of inmates had been reduced by 120 and staffing numbers increased. However, NPS remain a real concern, and the Prison Service is introducing a new testing regime across the country in April. Pray for the the police as they attempt to disrupt supply chains and take robust action against anyone found supplying or using NPS in prisons.
